==Command description== This operation will calculate uniqueness and entropy of the media represented by a media dump image. It's not affected my the image format compression if applicable.

==Command usage== Aaru entropy -d [true/false] -i -p [true/false] -t [true/false] -v [true/false] -w [true/false]

-d, --debug=[true/false] shows debug output ''(default false)''
-i, --input= path to the media dump image
-p, --duplicated-sectors=[true/false] besides entropy also calculates how many sectors have the exact same data in their user area ''(default true)''
-t, --separated-tracks=[true/false] separately calculates the entropy for each track dividing the media. Only applicable to certain kind of media (optical discs and digital tapes mostly) ''(default true)''
-v, --verbose=[true/false] shows verbose output ''(default false)''
-w, --whole-disc=[true/false] calculates the entropy for the whole media ''(default true)''

==Example== Aaru entropy -i mydisc.cue

==Operating system support== {| | FreeBSD | Yes |- | macOS | Yes |- | Linux | Yes |- | Windows | Yes |}
